The equation means that
 solv
e for m to get the ratio of n and m

so m + 4n = 2n +8m to g
et the ratio of n and m you'll just add all n and all m but the other m is not known just analyze and it means that m + 4n should have the same answer to 2n + 8m so 8 + 2 = 10 

just subtract 10 by 4 and you'll g
et 6 so the m is 6 

th
en follow the process 6m +8m = m : 4n + 2n  so the answer is 

14:6 b
